About the SEALMINER A2
The SEALMINER A2 is the base model of Bitdeer's second SEALMINER generation, air cooled and suited to locations with cheap power. It runs at 226 TH/s on 3,730 W, which is 16.5 J/TH, and comes in a single factory version. The A2 Pro Air delivers more hashrate at better efficiency in the same chassis, and the A2 Hydro reaches the same efficiency at nearly twice the hashrate on a water loop.
It runs on single phase supply at 220 to 277 V and uses about 89.5 kWh a day per unit. Like every air cooled miner it needs airflow and heat exhaust, hot and cold separation, and sound insulation near housing, since it runs at about 75 dB. The rated range is 5 to 45 °C ambient. Each unit measures 197 × 365 × 292 mm and weighs 15.5 kg, the same chassis as the A2 Pro Air, the A3 Air and the A3 Pro Air.

Air cooling. The simplest of the three routes and the lowest infrastructure cost. Sustained ambient above the rated range derates performance, so size the exhaust for the warmest week.
Energy only: 3,730 W rated power, 24 hours, one unit. Cooling overhead and PSU losses not included; no revenue assumptions.

Read before you buy the SEALMINER A2
The breakeven power price, and why we ask for yours first
Every machine has an electricity price above which it stops making money. Work that number out and most of the hardware decision answers itself.
Air, hydro or immersion: matching cooling to your site
The cooling route you pick decides which machines you can even consider, how loud your site is, and how much you spend before the first miner is switched on.
How loud is a mining site, and what to do about it
Noise is the most common reason a running site gets shut down, and the least often budgeted for. What the numbers mean, and what actually works.
